Arctic Silver

Arctic Silver CMQ2-25G 25g Ceramique 2 thermal paste

SKU CH-JCWX-PDTAE MPN CMQ2-25G

Ceramic-based compound lowers CPU temperatures by up to 10°C and remains stable from –150°C to 185°C

  • Lowers CPU load temps up to 10°C versus standard paste
  • Pure electrical insulator prevents short-circuit risk
  • Stable from –150°C to 185°C peak and 130°C long-term
  • 25 g syringe covers roughly 200 sq in at 0.003" layer
  • Innovative dispenser enables clean, precise application

25g Ceramique 2 thermal compound

Arctic Silver CMQ2-25G is a ceramic-based thermal paste designed for CPU and GPU heat-spreader interfaces. The polysynthetic suspension fluid holds tri-linear ceramic particles without metal content, making it a pure electrical insulator. Builders who prefer non-conductive compounds for first-time applications or dense circuit areas will find the formula straightforward to spread and wipe clean.

Replaces basic silicone pads or stock paste

Standard thermal compounds often leave microscopic air gaps that raise core temperatures under load. Ceramique 2 reduces full-load CPU temperatures by 2 to 10 degrees centigrade compared with those ordinary materials. The improvement is worthwhile whenever the existing interface has dried out, was applied unevenly, or uses a lower-grade filler that cannot sustain contact pressure over time.

Stable from –150 °C to 130 °C long term

The compound maintains its viscosity and particle distribution across a wide operating window, peaking at 185 °C without separating. A 25-gram syringe delivers approximately 9.2 cc, covering roughly 200 square inches at a 0.003-inch layer thickness. This consistency means repeated thermal cycles do not degrade the bond or pump out material from between the die and cooler base.

Questions about this item

How much surface area does the 25-gram syringe cover at the recommended layer thickness?

At a layer 0.003" thick, one 25-gram tube covers about 200 square inches, which is roughly 9.2 cc of compound.

What is the correct way to apply Ceramique 2 using the innovative dispenser, and what common step should be avoided?

Dispense a small amount directly onto the centre of the CPU heat spreader and let the cooler mounting pressure spread it evenly; do not manually spread the paste with a card or finger.

When will the thermal compound need to be replaced based on its long-term temperature rating?

The compound is rated for long-term use up to 130°C; if your CPU regularly exceeds this temperature under load, plan to replace the paste sooner than the typical multi-year interval.
